Event Description
|
Bha, backward approach, using exeter a case of young surgeon's first surgery.It means that it cured in about 4 minutes from the cement stirring.When young surgeon tried to fill cement into the marrow, it has already been cured and we have abandoned filling.(fast setting).In the facility, the cement is stored in cold storage.The agitation speed was one revolution per second (acm use) negative pressure was in the proper range.Therefore older surgeon's new cement and acm to install the implant.However, when surgeon agitated the cement, the condition of the cement felt a sense of discomfort for.As the young surgeon cement hardened, because the cement was filled at a relatively early stage after stirring for the second time, it is said that the feeling of discomfort with regard to the setting time is not felt.

Manufacturer Narrative

An event regarding (fast) setting time of the bone cement mix involving simplex p cement was reported.The event was not confirmed.Method & results: device evaluation and results: visual inspection and functional testing was completed on the three retained samples tested from the reported lot.The results were satisfactory and within specification.Medical records received and evaluation: not performed as no medical records were provided.Device history review: indicated that all product was manufactured and accepted into final stock with no reported discrepancies.Complaint history review: there has been one other similar event for the reported lot.Conclusions: the investigation concluded that the reported setting time issue cannot be duplicated.The mixing properties of the retained samples of the reported lot code were tested and show that all required specifications are met.The mixing characteristics and working properties of surgical simplex bone cements are influenced primarily by the temperature of the liquid and powder components at the time of mixing and by the temperatures of the utensils with which it contacts during mixing e.G.Mixing bowls, cement introducers etc.Generally, higher temperatures accelerate the polymerization reaction and lower temperatures delay it.Other factors which can affect setting time are mixing technique (speed, use of vacuum, centrifugation), thoroughness of mixing, complete utilization of all of the powder & liquid and care to avoid inclusion of any extraneous material such as blood or sterilization solutions into the mix.Mixing process/technique issues are highlighted in the ifu.Based on the laboratory results of the retain samples it is not possible to replicate this event.No further investigation for this event is possible at this time.If additional information becomes available this investigation will be reopened.
